Amplifying lens structure

Abstract

The invention discloses an amplifying lens structure. An image side end circular limiting channel, a first circular channel, a second circular channel, a third circular channel, a fourth circular channel and an object side end circular opening channel are sequentially arranged in an outer lens barrel from the image side to the object side, and the inner diameters of the channels are arranged fromsmall to large. A first biconcave lens, an inner lens barrel, a second biconcave lens, a first space ring, a third meniscus lens, a second space ring, a fourth biconvex lens, a third space ring, a fifth meniscus lens and a sixth biconvex lens which are sequentially close to one another in the direction from the image side to the object side are mounted in the outer lens barrel; and the inner sidewall of the circular opening channel at the object side end is in threaded connection with a compression nut used for pressing the sixth biconvex lens, so that the components from the first biconcavelens to the sixth biconvex lens are ensured to be close to each other in sequence so as to keep the distance between the lenses, and the lens is stable and practical.

Description

technical field [0001] The invention relates to a magnifying lens structure. Background technique [0002] With the widespread application of lenses in monitoring, industrial inspection, intelligent transportation, scanning and copying equipment, and photographic cameras, the demand for lenses is getting higher and higher. It is required that the imaging of the lens should be clear, and the quality of the lens with high requirements will definitely be used more. Lenses for optical imaging. However, it is difficult to ensure the stability of a group with a large number of lenses using a single pressure ring. Therefore, how to overcome the above-mentioned defects has become an important issue to be solved urgently by those skilled in the art. Contents of the invention [0003] The invention overcomes the disadvantages of the above-mentioned technologies and provides a magnifying lens structure. [0004] To achieve the above object, the present invention adopts the followin...
